During the electrolysis of molten sodium chloride, the time required to produce 0.10 mol of chlorine gas using a current of 3 amperes is: (a) 220 minutes (b) 330 minutes (c) 55 minutes (d) 110 minutes

2Cl —–> Cl2+2e

W = (E / 96500) x it

0.1 x 71 = (35.5 / 96500) x 3 x t

We get,

t = 6433.33 sec

t = 107.22 min

t = 110 min

Therefore, correct option is (d)
